It provides an up-to-date review on the geology, ecology, and physiology of coral reef ecosystems in the Red Sea, including data from most recent molecular studies. The Red Sea harbours a set of unique ecological characteristics, such as high temperature, high alkalinity, and high salinity, in a quasi-isolated environment. This makes it a perfect laboratory to study and understand adaptation in regard to the impact of climate change on marine ecosystems. This book can be used as a general reference, guide, or textbook.
Download or read book Climate Change Ocean Acidification and Sponges written by José Luis Carballo and published by Springer. This book was released on 2017-10-27 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: While sponges represent a very simple group of organisms, which are represented by over 8000 species, there is considerable interest in the increasing role they may play in future marine ecosystems. While we still have a comparatively limited understanding of how sponges will respond to ocean warming and acidification there is evidence that some species may have the ability to acclimate or even adapt to these stressors. This comprehensive collection of articles describes our current understanding of the impacts of ocean acidification and warming on sponges across multiple levels of biological organisation, and from the geological past to the present. With expert contributions from across the world this book represents the most up-to-date view on sponge responses to climate change. This book will be of interest to a wide audience of marine scientists and managers, who are grappling with how to manage, conserve and protect marine ecosystems.
Download or read book Sea Squirts and Sea Sponges of Britain and Ireland written by Sarah Bowen and published by Princeton University Press. This book was released on 2018-07-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea squirts and sponges are found in most seafloor habitats around the coasts of Britain and Ireland. Despite being the dominant life forms in many areas, these two groups of under-recorded marine animals are often confused with one another, and most divers and snorkellers can recognise and name very few species. In fact, around 500 species of Ascidiacea (sea squirts) and Porifera (sponges) have been described so far in British and Irish seas, corresponding to over 4% of the world’s total. This book is recommended reading for anyone who wants to identify and discover more about these fascinating and diverse animals. Rather than relying on the characteristics of preserved specimens, this guide uses marine photography and detailed underwater observations to concentrate on in situ features, allowing you to record species without collecting them. Most sea squirts found in Britain and Ireland’s shallow waters are included, together with the most easily recognised sponges. Whether you are a student, a diver, a rockpooler or simply an enthusiast, this is an essential companion. ● Over 115 species described in detail with in situ photographs to help with underwater recognition ● Information on size, depth, habitat and distribution ● Key distinguishing features and areas of confusion in identification highlighted ● Details of body structure, life histories, digestive and reproductive processes ● Information about predators, interactions between species, non-native and problem invasive species
Download or read book Sponge Bioerosion and Habitat Degradation on Indonesian Coral Reefs written by Joseph Marlow and published by . This book was released on 2017 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract:]Coral reefs are among the most diverse ecosystems on the planet, yet they are also sensitive to anthropogenic disturbances that can degrade these systems. On many degraded reefs, large increases in bioeroding sponge abundance have occurred. On healthy reefs these sponges contribute to species diversity and habitat complexity, however there is growing concern that their proliferation on degraded reefs could lead to a state of net-erosion. In the Southeast Asian Indo-Pacific, the ecology of bioeroding sponges in relation to coral degradation has been poorly studied compared to other coral reef regions. This thesis aims to increase our understanding of the ecology of these sponges in the Wakatobi region of Indonesia, and their likely trajectory if reefs continue to degrade in the region. My first research chapter aimed to identify the common bioeroding sponge species of the Wakatobi. This was achieved through in-water surveys, and subsequent spicule and phylogenetic analysis. This resulted in the identification of eight commonly occurring Wakatobi bioeroding sponge species, two of which are described for the first time. The assemblage composition was distinctly different from the only other bioeroding sponge study in Indonesian waters (Calcinai et al. 2005), highlighting the need for more clionaid taxonomic information from the region. Having identified the common bioeroding sponge species in the region, my second chapter assessed the major environmental drivers of the abundance and assemblage composition of these sponges. Abundance surveys were conducted at 11 reef sites characterised by different environmental conditions and states of reef health. Bioeroding sponges occupied 8.9% of suitable substrate, and differences in abundance and assemblage composition were primarily attributed to differences in the availability of dead substrate. However, abundance was lowest at a sedimented and turbid reef, despite abundant dead substrate availability.

Download or read book Sponges written by Lisa Goudie and published by Museum Victoria. This book was released on 2013 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: We might think of sponges as bathroom objects but the real living animals are far more interesting. They come in all shapes and sizes, occur in all oceans of the world, and have amazing lives. Sponges have lived in our oceans for 600 million years. Ancient forms even built reefs bigger than the Great Barrier Reef. Today, sponges help clean our oceans, are experts are chemical warfare and can rebuild themselves after being torn apart. Some even live for 2000 years. There is still much to learn about the diversity and biology of sponges in southern Australian waters, with many species still waiting for formal scientific description. This guide introduces naturalists, beachcombers, divers and others to sponge species commonly encountered in southern Australia.

Available in PDF, EPUB and Kindle. Book excerpt: Nudibranchs of the Coral Triangle became the only guide to nudibranchs on the market with an up-to-date 2022 taxonomy after its major update (November 2022) This book is a field guide, an assistant for the identification of nudibranchs species in the region. It is designed for divers, underwater photographers. The book presents 1060+ species nudibranchs that can be found and photographed in depths and regions accessible to recreational diving. Photographs, showing color variations and age differences are included. A lot of species covered by this guide have never before appeared in field guides or popular books. Compact text blocks provide information about Common name, Latin name, family, geographic distribution, size, and the most distinctive features. An extensive photo index at the beginning of the book helps you to find the right group of nudibranchs, especially for readers who have not yet mastered their names. Nudibranchs or sea slugs occur throughout the world’s oceans and are present in many marine habitats. The greatest diversity of species is found in the Indo-Pacific tropics with a concentration of species within the Coral Triangle (CT), encompassing the waters of six Southeast Asian countries: Indonesia, Papua New Guinea, Philippines, Malaysia, Timor-Leste and Solomon Islands. This global epicenter of marine biodiversity covers only 1.6 percent of the planet’s oceanic area, but attracts an increasing number of divers and underwater photographers, including nudibranch lovers.

Available in PDF, EPUB and Kindle. Book excerpt: Chemical signals among organisms form "a vast communicative interplay, fundamental to the fabric of life," in the words of one expert. Chemical ecology is the the discipline that seeks to understand these interactions-to use biology in the search for new substances of potential benefit to humankind. This book highlights selected research areas of medicinal and agricultural importance. Leading experts review the chemistry of Insect defense and its applications to pest control. Phyletic dominance--the survival success of insects. Social regulation, with ant societies as a model of multicomponent signaling systems. Eavesdropping, alarm, and deceit--the array of strategies used by insects to find and lure prey. Reproduction--from the gamete attraction to courtship nd sexual selection. The chemistry of intracellular immunosuppression. Topics also include the appropriation of dietary factors for defense and communication; the use of chemical signals in the marine environment; the role of the olfactory system in chemical analysis; and the interaction of polydnaviruses, endoparasites, and the immune system of the host.

Download or read book Diversity of Sponges Porifera from Cryptic Habitats on the Belize Barrier Reef Near Carrie Bow Cay written by and published by . This book was released on 2014 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Caribbean barrier reef near Carrie Bow Cay, Belize, has been a focus of Smithsonian Institution (Washington) reef and mangrove investigations since the early 1970s. Systematics and biology of sponges (Porifera) were addressed by several researchers but none of the studies dealt with cryptic habitats, such as the shaded undersides of coral rubble, reef crevices, and caves, although a high species diversity was recognized and samples were taken for future reference and study. This paper is the result of processing samples taken between 1972 and 2012. In all, 122 species were identified, 14 of them new (including one new genus). The new species are Tetralophophora (new genus) mesoamericana, Geodia cribrata, Placospongia caribica, Prosuberites carriebowensis, Timea diplasterina, Timea oxyasterina, Rhaphidhistia belizensis, Wigginsia curlewensis, Phorbas aurantiacus, Myrmekioderma laminatum, Niphates arenata, Siphonodictyon occultum, Xestospongia purpurea, and Aplysina sciophila. We determined that about 75 of the 122 cryptic sponge species studied (61%) are exclusive members of the sciophilic community, 47 (39 %) occur in both, light-exposed and shaded or dark habitats. Since we estimate the previously known sponge population of Carrie Bow reefs and mangroves at about 200 species, the cryptic fauna makes up 38 % of total diversity.

Download or read book Marine Natural Products Chemistry written by D. Faulkner and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the lectures presented at the NATO sponsored conference on "Marine Natural Products" held in Jersey, Channel Islands, U. K., October 12-17, 1976. The intent of the organising committee was to encourage a dialogue between organic chemists who study the metabolites of marine organisms and biolo gists, ecologists, and pharmacologists who study the effects of these metabolites on other organisms. A feature of the conference was the three workshop sessions on chemotaxonomy, applications of marine natural products, and chemical communication. The papers presented at the conference contain a mixture of original research in marine natural products and reviews of some of the more important subjects. The biologists were asked to present papers which could initiate new directions for marine natural products research. Their contributions to the meeting were warmly received by the chemists in the audience. We hope that this volume contains not only past and present research but a suggestion of future research trends. The conference was first suggested by Dr. E. D. Goldberg. The organising committee, Drs. G. Blunden, D. J. Faulkner, W.
Download or read book Systema Porifera written by John N.A. Hooper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.
